PRODUCT USE QUIKRETE® Rapid Road Repair® can be used to replace sections of streets or highways, runways or taxiways of airports and other applications where quick return to usage is desired. In most cases, traffic can be resumed in less than 1 hour after patching. QUIKRETE® Rapid Road Repair® is made from specially blended cement with carefully graded aggregates to provide a permanent patch. It also contains AR glass fibers for improved flexural performance essential for applications of severe vibration as in the repair of bridge decks. An un-fibered version of this product is also available. SIZES • QUIKRETE® Rapid Road Repair® - 50 lb (22.7 kg) or 67 lb (30.4 kg) bags YIELD A 50 lb (22.7 kg) bag of QUIKRETE® Rapid Road Repair® will yield 0.40 cu ft (11 L) of material. A 67 lb (30.4 kg) bag will yield 0.54 cu ft (15 L).

QUIKRETE® Rapid Road Repair® meets the requirements of ASTM C928 Grade R3. It can be modified to meet specific requirements of the Department of Transportation in various states. INSTALLATION SURFACE PREPARATION • Remove all spalled areas and areas of unsound concrete and patching • The hole should have a vertical edge of 1/2" (12.7 mm) or more, formed by use of a pneumatic jackhammer or sawing. Holes should be chipped out to create a new, sound substrate • After the chipping process is completed, the repair area must be cleaned by water blasting or other suitable method • Dampen holes with clean water before patching. No puddles of water should be left in the hole MIXING • Use 3/4 gal (2.8 L) of water per 50 lb (22.7) bag or 1 gal (3.8 L) of water per 67 lb (30.4 kg) bag • All tools and equipment used in the mixing and finishing process should be clean

PRODUCT DESCRIPTION QUIKRETE® Rapid Road Repair® is a fast-setting, rapid-hardening mortar designed to repair concrete highways, bridge decks, concrete parking lots and concrete floors.

• Place water in mixer. While mixer is running, add contents of bag • Mix 4 to 5 minutes. The mix will appear stiffer than normal concrete • Place in a wheelbarrow or other transporting vehicle. Place the mixture immediately after the mixing is completed Note - Working time is 10 - 20 minutes and will fluctuate: shorter time during severe hot weather and longer time during cold weather.

This is particularly important around the edges • Screed and finish patches with hand tools to create a surface finish equivalent to the existing slab finish

CURING No curing membranes or compounds are required. Traffic can be allowed over the patch in approximately 1 hour if the temperature is 70 degrees F (21 degrees C) or above. Cure under ambient conditions. Do not moist cure. AGGREGATE EXTENSION For deep patches, QUIKRETE® Rapid Road Repair® may be extended with up to 25 lb (11.3 kg) of minus 1/2" (12.7 mm) coarse aggregate per 50 lb (22.7 kg) bag or 33 lb (15 kg) per 67 lb (30.4 kg) bag. Water content must be adjusted depending on the moisture content of the aggregate. Adjust as needed to achieve a slump of about 3" - 4" (76 - 102 mm). Typical test results are found in Table 2. TABLE 2 PRODUCT EXTENSION OF QUIKRETE RAPID ROAD REPAIR® 1 Property & test Typical value for extended product Compressive strength, ASTM C39 1 hr 2380 psi (16.4 MPa) 3 hr 2750 psi (19.0 MPa) 24 hr 6150 psi (42.2 MPa) 1 Product extended with 50% by weight minus 1/2" (12.7 mm) diameter coarse aggregate. PRECAUTIONS During extremely hot or dry conditions, cold water should be used to maintain mix at a moderate placement temperature. QUIKRETE® Rapid Road Repair® must be properly placed in a space surrounded by sound, high quality previously hardened concrete. Do not subject to de-icing salts for at least 7 days after placement.
